Usually cross-posters are trolls looking to be fed by the
uninitiated, but, at the possible expense of feeding a troll,
Old Man will take a small bite. Would V.Gopal please
clarify the meaning of "quantifier", and how one "eliminates
such?
A necessary condition for the existence of space and time
is a space-time metric which is a quantitative expression
that relates space and time via elementary physical
constants. The only parameter required in Einstein's theory
of special relativity, which completely describes flat space
-time or "empty space", is the invariant speed of light. A
sufficient condition might require the presence of a field,
wherein space-time curvature is finite, and whereby, an
additional parameter, the universal gravitational constant,
is required for the existence of space and time.
None of the ramblings above constitute a physical theory
since it contains no predictions that are falsifiable by
experiment. It is just metaphysics, wherein nothing ever
sticks and endless argument ensues. Old Man thinks that
neither V.Gopal nor anyone else can do any better.
